BUNDLE TIER.

Application filed November 8, 1923. Serial no. 673,467.

residents of Blissi'ield, in the county of Lena twee and State of Michigan, have invented anew and useful Bundle Tier, which invention is fully set forth in the following specification. 7 @ur invention has for its object to provide an eiiicient manually operated bundle tier that may be made at a low cost and sold at a correspondingly low price. By our invention is provided atier whereby a bundle, when placed in a position on the tier will be partially wrapped with a string or twine orsimilar article, that is hereinafter broadly referred 1 to as string, and, upon continued movement of the package means will be operated for drawing the string tightly about the package and tying-the string. After the package has been placed in position on the machine and partially wrapped with the string, a part of the tier is moved with the packa'ee which causes the completion of the wrapping and the tying of the string. j For convenience operation the wrapping and tying mechanism are supported on an oscillatable member, so that when the package is placed in position and the member is oscillated, the string is wrapped about the package and tied.

then features and advantages of our invention will appear in the following description and upon examination of the accompanying drawings.

The invention may be contained in structures of different forms. practical application of the invention, we have selected a bundle tier containing the invention and shall describe it hereinafter. The structure selected is shown in the drawings.

The particular construction shown inthe drawings is provided with a bed plate 1 to which is pivotly connected the supporting frame for the tying-and wrapping mechanisms. ltiov em'ent of the supporting frame relative to the be'd plate actuat'es the wrap ping and tying ine'chani'sms, the actuating means being connected to the bed plate.

The rapping and tying mechanism for wrapping, tying and severing the cord a is supported in the frame 2 which comprises number of enclosing shells or chambers for parts of the mechanism. It is piv otly supported by the pin 3 (Fig. 6) that is located in a hole bored in a boss 4 formed on the frame 2. The frame as provided with an arm 5' on which the table (3 is supported and in position convenient for receiving the package. One edgeof the table 7 is also convenient forlnanu'ally causing a swinging movement of the frame 2, as byplacing the palm of the hand against the edge 7 of the table and. pushing itaway from the opcrator, but at thesame time, holding the package in position onthe table. A spring 8 is connected to the frame 2 and to a post 9 havinga suitable cushioned bumper 10 that limits the return novement of the frame 2 by the operation of the spring 8. hen the package and the table aresu' ung on the pivot pin 3 the wrapping mechanism and tying mechanism are operatedby elements that are connected to the bed plate 1.

The tying mechanism is located at the outer end of the arm 5, beneath the forward edge of the port-ion'bed or table 6 and in the chamber 11. The tying mechanism is of the type described in application Serial No. (360,104- liled August 30th, 1923, wherein a swinging arm forms a loop within a loop engaging head and a tying bill forms a loop in two portions ofv the string and engages two other portions of the string and draws \Vhen the package is placed on the table 6 it is pushed against the string extending from the needle to the engaging head which partly wraps the string around the package. The needle member is then swung down underneath one ed 'e of the table while the string is drawn taut and tied by the tying mechanism.

The needle and the tying mechanism are operated by the movement of the frame 2 relative to the bed plate 1. The frame has a shaft 12 which is located in the arm 5 of the frame 2. The shaft has a clutch member 13 secured thereto by the pin 14. The co acting clutch member is located on the shaft 12 in position to engage the member 13 when the member 15 is rotated in one direction. The clutch member 15 is provided with a jaw 16 that sets in to a recess formed in the member 13. The jaw 16 is provided with faces 17 that are inclined to the direction of movement of the jaw 16 which causes the members 13 and 15 to engage or to separate, when the member 15 is rotated in one direction or the other. When the member 15 is rotated in one direction it causes the rotation of the shaft 12. Rotation of the shaft in the opposite direction is prevented by a suitable engaging means.

Rotation of the member 15 is produced by the chains 18 and 19 which are located at 'such an angle to the shaft 12 as to draw the member 15 towards the member 13 and thus insure engagement between the two members. A spring 19 may also be used to co-operate in securing inter-engagement between the members 13 and 15. The chains 18 and 19 are connected to the member 15 by means of the pin 20 that extends through the bosses or projections 21, 22 and 23 formed on the member 15. The chains are connected to the bed plate 1 through the medium of a rocker bar 24: which is pivotly connected to the bed plate by means of a machine bolt 25. The chains 18 and 19 are connected to opposite ends of the rocker bar 21. One end of the rocker bar 24v. is connected by a link 26 to the frame 2 at a point near its axis of rotation on the frame 2, the points of connection between the moving parts being such as to produce such rocking movements of the rocker bar 2a that the chains 18 and 19 will maintain substantially a constant angle to the axis of the shaft 12 as the frame is oscillated about the pivot pin 3, within, of course the limitations of the angle that frame 2 is permitted to move which is substantially the angle of which the rocker bar is a chord. The spring 8 normally holds the frame 2 against the cushion stop 10 located on the upper end of the post 9 and draws the frame 2 towards the post end when the frame 2 is moved from the frame. The chain 19 which is connected to the pin 20 and to a post 27 located on one end of the rocker arm 24c causes rotation of the member 15 in a direction such that the jaw 16 will engage the member 13 and cause rotation of the shaft 12.

The tying mechanism 28 and the needle 29 are connected to the shaft 12. The needle passes over the bundle to the tying mechanism 28 to draw the string around the package and to deliver it to the knotting mechanism located below the package and at the edge of the table 6. During this operation the movement of the shaft 12 may be varied in its rate by the irregular formation of the clutch member 15 from and onto which the chains unwind and wind. The shape of the member 15 is such that in any given part of the movement of the frame 2 there will be a slower or quicker movement of the shaft 12 according as the chain 19 is being delivered from a high part or a low part, that is a part more remote from the axis of the shaft 12 or a part closer to the axis of the shaft 12. Thus when the chain 19 is being de livered from the surface of the part 29, the relativei'i'iovement of the shaft 12 is slower than when it is being delivered from the surface of the part 30 which gives more of a leverage to the chain and enables the shaft to overcome a greater force. This occurs during the knotting and cutting of the string when the greatest resistance in the operation of the machine is met.

The needle 29 is connected by means of the bent bar 31 to the arm 32. The arm 32 is connected to the shaft 33 supported in the shell 34. A. rocker arm is connected to the shaft 33 and to a link 36. The link 36 is connected to the crank 37, that is connected to the shaft 12. The length of the rocker arm and crank 37 is such as to produce rocking movements in the arm 32 and, consequently, in the needle when the shaft 12 is rotated. Thus during rotation of the shaft 12 the arm 32 and the needle 29 are swung to their lowermost positions and then back again and the chain 18 is wound on the member 15. The shaft 12 is rotated by pushing on the frame 2 such as, pressing against the edge of the table 6 and cans ing the chain 19 to rotate the member 15 which engages the member 13 that is keyed to the shaft 12. Reverse rotation of the shaft 12 is pr vented, when the frame 2 is returned, by the operation of the spring 8, by the dog 38 which is pivotly connected to the lower end of the link 36. The shell 34: has an opening 39. The edge of the opening on the followingside of the link as the link is moved by the crank 3? will be en gaged by the end of the dog 38, when the frame 2 is returned by the spring 8. The return rotative movement of the member 15 is produced by the chain 13, which is connected to the pin 20 and to the post at) located on the end of the rocker bar 2%.

I the form of a bobbin. The bobbin may be placed on the plate 41. A pin/l2 may be located in the center of the plate 4L1 for maintaining the bobbin on the plate. The string is fed up through a hole 43 formed in an arm 14 located on the top of the shell 3%. It may be again fed through a hole 15 to a tension member 16 and through the eye 47 located in the end of the rod 48, in proximity to the needle When the needleis in the uppermost position and in the vertical plane of the movement of the needle. The string may then be threaded through holes formed in bosses .49 formed on the needle and then through the eye 50. It is carried down to the knotter plate 51 and to the loop engaging head 52 Where it. is caught. A package is pushed against the string until it is placed in position on the table 6, the

string being drawn by the tension produced by the friction of its movement through the holes in which it is located. The table 6 is then pushed around so as to movethe needle down underneath the front edge of the table, the needle drawing the string taut, until it. is engaged by the loop engaging head and knotted by the knotting mechanismavhereupon the arm immediately returns. By this timethe frame has completed its stroke and is then returned by the action of the spring 8 to its original position.
